From Edwards’ sermon, “Value of Salvation.”
There is a time coming that there will be a very great change in the world: those nations which now are covered with the darkness of heathenism and idolatry, or other false religions, shall be enlightened with the truth, and there shall be a more extraordinary appearance of the power of godliness amongst those that profess it, when God’s spirit shall be poured out on old and young, and the knowledge of God shall cover the earth “as the waters cover the seas” (Is. 11:9); “When they shall teach no more every man his neighbor, and every man his brother, saying, Know the Lord; for they shall all know him, from the least to the greatest”; “When the fullness of the Gentiles shall come in and all Israel shall be saved” (Rom. 11:25-26). These, and suchlike expressions, signify the all nations shall be Christianized and be visibly holy, and that multitudes–great multitudes all over the face of the earth–shall be brought to the saving knowledge of God.
